A tropical storm formed off the east coast of the United States this afternoon, but forecasters do not expect it to be a threat to the U.S.

Tropical Storm Claudette is well out to sea east of the Delmarva Peninsula. The National Hurricane Center says the system has sustained winds of 50 mph and is moving to the northeast at 15 mph.

That motion is expected to continue, keeping it away from the mainland U.S.

The long-range forecast calls for the system to make landfall in the Canadian Maritimes as a tropical storm or depression, with high waves being the most notable effects.

"[Claudette] could still bring swells to the East Coast," FOX 13 meteorologist Lindsay Milbourne blogged. "The Wave Watch III Model shows wave heights building to 4+ feet off the Carolinas and up to 10 feet south of Nova Scotia Tuesday afternoon."
